| PITFALLS
OF MEDICATING APATHY [ back
to What's New ]
A common sequelae of frontal lobe injury is apathy or loss
of ability to spontaneously initiate activity. Persons with
this executive function disorder symptom cannot set themselves
in motion, and need constant reminders from others to do just
about anything, even eat a meal. In the January 1999
edition of Brain Injury, it was reported that administration
of the drug Amantadine, which stimulates extra release and
utilization of dopamine, helped a female patient with bilateral
front lobe injury overcome her apathy. However, the higher
dosage required to achieve this led to the opposite problem
of agitation, impulsivity and aggression. Lowering the dose
stopped the side effects, but she became apathetic again.
Fine tuning the dosage to obtain the benefit while avoiding
undesirable side effects is no easy matter, as this report
shows. The authors recommend further trials of amantadine
and other dopamine agonists such as bromocriptine and sinemet
in hopes of finding the right balance of meds.
